2. The simple and clear treatment of NOTATION and NUMERATION. 3. The early introduction of the DECIMAL POINT, (pp. 15, 16,) and the explanation of the values expressed by figures at the right of the point, (p. 52.)

4. EXCHANGE of COMMODITIES, BILLS AND INVOICES, ACCOUNTS. LEDGER COLUMNS, (pp. 72, 78,) and various useful applications. (pp. 142, 178, 186, 187, 202, 263, 212, etc.)

8.

The METRIC SYSTEM of WEIGHTS and MEASURES is in its proper place, in the body of the work, (p. 155,) and referencet made to the same in subsequent parts of the book, (pp. 164, 166, 170, 187, 247, 283, etc.,) as urged by PROF.

13. The ANALYTICAL PROCESSES throughout, making written Arithmetic in all its steps intellectual, never before to the same extent attained in any work.

14. The thorough enforcement of educational results, by means of systematic REVIEW QUESTIONS and EXERCISES, (pp. 32, 54, 58, 122, 186, etc.)

TIME SAVING AND LABOR SAVING.

It will be noted that this work with GREENLEAF'S NEW PRIMARY, and NEW ELEMENTARY, or New Intellectual ARITHMETICS, forms a clear, practical, comprehensive system,

COMPLETE IN ONLY THREE BOOKS,

and is believed to be, the cheapest, most convenient and productive, that has ever appeared.

By its use, in comparison with certain crude, overloaded, and long spun out courses, of five or more books, with such catch penny accompaniments, as Table Books, Dictation Cards, Books of Principles, Keys of Answers, Grammar School Editions, etc... it is safe to say that the learner may not only make better progress, but, at least,

SAVE TWO YEARS OF VALUABLE TIME.
